ALBERT PETTERSON, OF ST. PAUL, MINNESOTA.

ADJUSTABLE STOVEPIPE-S U PPORT.

SPECIFICATION forming part of Letters Patent No. 476,815, dated June 14, 1892.

Application filed February 2, 1891. Serial No. 379,899. (No model.) 1

To all whom it may concern.-

Be it known that I, ALBERT PETTERSUN, of St. Paul, Ramsey county, Minnesota, have invented cert-ain Improvements in Adjustable Stovepipe-Supports, of which the following is a specification.

My invention relates to improvements in attachments to stovepipes for connecting them to the ceiling or other support, its ob ject being to provide a device which is readily attached to or detached from the pipe and the Wall or ceiling, and may be adjusted to any desired length, so as to bring the pipe into the desired position.

To this end my invention consists in a twopart clasp to surround the pipe and an extensible arm to connect said clasp with a supporting-hook, the length of the arm being adjusted as desired.

My invention further consists in the construction and combination hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of my improved support. Fig. 2 is a side elevation of the same. Figs. 3 and 4 are partial details of the arm and extensionpiece, and Figs. 5 and 6 are enlarged details of the spring-catch for locking together the arm and extension-piece.

In the drawings, 2 represents a substantially semicircular band or strap of sheet metal provided at one end with an eye or opening 4 and at its other end with a hook 6, this strap forming one member of the pipe-clasp. The other member 8 is of substantially the same form, having, also, an eye 4 and hook 6, by means of which the two partsare readily connected together, thus forming a circular band for inclosing the pipe. The member 2 of the clasp is slipped through a loop 12, turned at right angles to the body of the arm lat, also preferably made of sheet metal, so that the arm extends at right angles to the tangent of the strap 2 at the point of its connection with the arm. At the outer end of the arm is provided an opening 16 in the form of a four-pointed star, or a cross formed by the intersection of alongitudin'al and a trans- Arranged in this opening is a Wire spring-catch 18, bent upon itself with its ends 30 outturned and slipped through the open ing lo, the spring of the body tending to spread the ends, and thus to hold them at the extremities of either slot. of the opening, so that the catch will be held with its plane either at right angles or in line with the arm. Sliding upon this arm is a longit1ulinally-slotted extension-stri p 22,11aving at its lower end a clasp 2st, partially emlnacing the arm, and having its outer end bent upon itself to form a transverse eye 26, adapted to he slipped upon a right-angled hook 28, secured to the ceiling or wall. The longitudinal slot 30 of the extension-piece is provided. at intervals with oppositely-arranged notches 32. corresponding approximately to the size of the transverse slot of the opening in the end of the arm to receive the spring. This extension-picce being slipped upon the arm, the spring-catch is inserted into the opening 16 and turned to stand in line with the arm, when it can he slipped through the slot in the extension-piece, and then, being given a quarter-turn, will spring outwardly into the notches of the slot and hold the extensionpiece fixed upon the arm. The position of the parts is adjusted bysimplygivingthe springcatch a reverse quarter-turn and sliding the parts upon each other to thedesired position, when the catch is again turned to lock them together. This attachment may be used as a support for suspending a horizontal pipe or as a lateral brace for a vertical pipe.

The device, as described, may be attached to different sizes of pipes by simply using a detachable clasp member of such size as to inclose the pipe, the members bonding to adapt themselves to the surface of the pipe.

I claim- 1. In a device of the class described, the combination of a two-part clasp to surround the pipe, a sheet-metal arm rigidly connected to one member of the clasp,a sheet-metal extension piece sliding upon said arm and adapt-ed to be attached to a hook or other support having a longitudinal slot and oppositely-arranged notches in the sides of the slot, and a spring-catch adapted to be inserted through said slot and turned transversely thereof to engage said notches and to lock the extension-piece upon said arm, substantially as and for the purposes set forth.

2. The combination of the semicircular sheet-metal clasp, members 2 and 8, adapted to surround the pipe and to be connected end to end, an arm having a loop firmly engaging; the memberfi and having an opening formed by intersectingv longitudinal and transverse slots therein, a spring-catch arranged in said opening, and the extension-piece 22, sliding uponsaid arm and adapted to be connected to a suitable support and having;v theJongitmtlinal slot 30 and the notehes32 in the sides of said slot, adapted to receive said spring-catch, substantially as and for the purposes set forth.

3. In a device of the class described, the combination, with the pipe-clasp, of a tWopart attachment to said clasp, comprising a sheet-metal arm connected to the clasp and a sheet-metal extension-piece slidingupon said arm and connected to the'support, one of said members having an opening therethrou gh formed by the intersection of a transverse and longitudinal slot and the other member having a longitudinal slot and oppositely-arranged notches in the sides of said slot correspending in size to the transverse slot of the opening in the other member, and a laterallyexpanding spring-catch held in said opening in one member and extending through the slot in the other member and adapted to engage the notches of its slot, substantially as described.

\Vituess my hand this Qith day of January, 1891.

ALBERT PETTERSON.
